Justin McKey, 25, posted bond late Tuesday. He was charged with hit-and-run and manslaughter.

"Instead of vehicular and negligent homicide he was charged with manslaughter which is up to 40 years," said legal analyst Robert Jenkins.

McKey also has ties to city hall. WDSU has learned that his mother does human resources work in the Information Technology and Innovation Department and has been a city employee for more than 20 years.

Legal experts said that should have no bearing on this case.

"This prosecution, if goes forward, will take place in state district court, not in any city municipal court," said Loyola law professor Dane Ciolino.

Meantime, at the 2nd District Police Station, a memorial was set up for officer Rodney Thomas. Friends, colleagues and strangers laid flowers on his patrol car.

Inside the station, a candle burns for the officer killed in the hit-and-run.
